Frequency converters

Power electronics solutions for energy, industry, and infrastructure.

Permanent solutions

F&S offers a broad portfolio of power electronics solutions for your application - from compact controllers for the excitation of your synchronous machines to optimized speed and torque control for your multi-megawatt drive projects. Based on an intelligent, modular design concept, our solutions are custom-fitted to customer requirements: From soft starters and start-up converters for starting large machines, self-commutated voltage source converters for drives with high dynamics, all the way to load-commutated current source converters for continuous operation of controlled, high-power synchronous machines. The applications are manifold: building materials, mining and minerals, energy, water, metals, marine and chemical, the oil and gas industries, and so on.

Soft-starters

With our soft-starters, you can easily master the power-limitation required during the start-up of medium-voltage drives.

Excitation systems

Our excitation systems are holistic solutions for effective system operation. We adapt each system to specific customer requirements, resulting in sophisticated, user-friendly designs with high maintainability.
